Place the three dot matrix displays as shown in the video, ensuring the arrow on each display is pointing upward.
Connect the displays using a 40 cm IDC cable:
- Connect the left IDC header of the top display to the right IDC header of the middle display.
- Connect the left IDC header of the middle display to the right IDC header of the bottom display.
- Finally, connect the left IDC header of the bottom display to the IDC header of the Scoreduino module.
We offer two types of Scoreduino modules: one with a through-hole Atmega chip (SCOREDUINO-DMD) and another with an Arduino Pro Mini. Either module will work the same way.
Now, connect the power cables:
- Connect the red wire to the VCC pin and the black wire to the ground pin on the power sockets. VCC provides +5 volts.
- Power all displays using these cables.
- Connect the power cable to the Scoreduino module. Use the blue-colored screw terminal near the IDC header on the module.
Important: Incorrect connections can permanently damage the Scoreduino module. For a 5V- 6A power supply, you can connect it to the DC barrel or use the screw terminal marked as IN. The provided DC barrel can be connected to this screw terminal.
For the enclosure:
Use a 60 cm by 40 cm MDF board (Medium-Density Fiberboard) or plywood.
Cut four pieces of timber for the sides of the board, each about 6 cm wide and 2 cm thick. This thickness makes it easier to hammer nails and secure them to the board.
- Make a hole at the bottom right of the scoreboard to allow the IDC cable to pass through. Use a drill, chisel, or special cutter for this.
Create a matching hole in the box and attach it to the side of the scoreboard, aligning the holes. Secure the box with screws and cover the screws with tape to prevent contact with the Scoreduino module.
Place the Scoreduino-DMD and Bluetooth modules inside this box for easier removal and ventilation.
To mount the display panels:
- Attach small pieces of timber or sticks to the board to raise the display panels, allowing space for cable management underneath.
- Use the provided strips to secure the displays to the board, maintaining a 2 to 3 cm gap between displays for visibility.
- Fix a 60 cm by 30 cm acrylic sheet on top of the board.
Optionally, use aluminum frames to cover the sides of the scoreboard.
For hot weather use:
Hello, how many modules can I connect with this board? I need one that can connect 5.
